## Long description

HP DDR4 64GB Quad Rank LR memory module (MPN P18451-B21-RFB) is a high-capacity server-grade DIMM designed for reliable performance in enterprise servers and professional workstations. The 64GB capacity combined with a Quad Rank LR (Load-Reduced) architecture delivers increased memory density while maintaining signal integrity and compatibility with systems that support LR DDR4 modules. This HP memory module is intended to provide stable operation under sustained workloads and to support applications requiring large memory pools.
Advantages
The HP 64GB DDR4 Quad Rank LR module provides high memory capacity suitable for virtualization, large databases and memory-intensive computing. The Load-Reduced (LR) design reduces electrical load on the memory controller, allowing more ranks per channel and increased total system memory. The module is manufactured to HP specifications to ensure compatibility and reliability in certified server platforms and supports standard DDR4 features for performance and stability.
Suitable for
 Enterprise servers running virtualization platforms (VMware, Hyper-V, KVM)
 Database servers and in-memory databases
 High-performance workstations for simulation, CAD, and data analysis
 Environments requiring high-density memory configurations
Key specifications
 Brand: HP
 Model / MPN: P18451-B21-RFB

 Capacity: 64GB
 Target category: Memory module for servers/workstations
How to use
Install the HP DDR4 64GB Quad Rank LR module into a compatible server or workstation DIMM slot following the system vendor's service manual and static-discharge precautions. Ensure the target system firmware and BIOS support DDR4 LR quad-rank modules and that memory population guidelines (channel balancing, slot ordering) are observed. After installation, verify system POST and confirm the operating system recognizes the full 64GB capacity. For multi-module configurations, follow the platform-specific rules for ranks per channel and maximum supported memory per CPU.
Usage recommendations
Use this HP 64GB DDR4 Quad Rank LR module in systems validated by HP or the server vendor for LR modules. Confirm compatibility with motherboard and CPU memory controllers, and update firmware/BIOS where necessary. For best results in multi-socket and high-density configurations, install modules according to the server vendor's memory population guidelines and perform memory diagnostics after assembly.
